MagnaFlux Zyglo ZL-37 Post Emulsifiable Fluorescent Penetrant (01-3188)

Due to supply chain disruptions caused by Covid-19, Magnaflux is transitioning to 1-gallon containers for all existing uses of aerosols on this product line.

The Magnaflux Zyglo® ZL-37 Post Emulsifiable Fluorescent Penetrant's formulation has been designed to be impervious to water to protect it from over washing and permit more penetrant to remain in discontinuities for improved detection of small defects. It and other post emulsifiable penetrants require the application of a lipophilic or hydrophilic emulsifier to render them washable with water.

Zyglo® ZL-37 fluoresces a bright greenish-yellow under ultraviolet radiation. Use of an ultraviolet light source with a peak wavelength of 365 nanometers, such as the MAGNAFLUX® ZB-100F fan-cooled black light, is recommended.

Zyglo® ZL-37 penetrant meets OSHA requirements for Class III B liquids due to its high flash point and can be used in open dip tanks.

Specifications Compliance: AMS-2644,ASTM E 1417,MIL-STD-271, ASME B & PV Code, Sec. V, MIL-STD-2132, Boeing BAC 5423 PSD 6-46 or 8-4, AECL, ASTM E 165, Boeing PS-21202

Applications: Zyglo® ZL-37 is ideal for titanium turbine components, investment castings and other high stress critical components where detection of fine, tight discontinuities is required.

Classification: Type 1, Method B Penetrant when using ZE-4B emulsifier.
Type 1, Method D Penetrant when using ZR-10B (20%) remover.

Sensitivity Level: Level 4 - Ultra-High Sensitivity

Due to shipping regulations, aerosols must ship via ground delivery.
